This is probably the best 7 inch Reel to Reel Akai put out. With the Glass and Xrystal Play and Record heads, with proper maintenance, they last forever. The direct drive reel and capstan motors are real workhorses.
It has 4 chl or 2chl recording with sound on sound. So you can record a track and then come back and lay down more on that track.
In 2chl mode it has auto reverse for playback. But does not have reverse recording ( the reason I gave it a 9 instead of a 10 rating). I've owned one or more since 1974 and have only had to have repairs once. It is a reliable deck.
